Application filed December 15, 1917.

To aZZ whom it may com com Be it known that I, HUGH l). FOLEY. a

, citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of'lvlmnesota, have invented certain new and useful improvements n SupplementalT iVheel-Rims; and I do hereby de-' clare the following tobe a full, clear, and exact descriptionof the invention, sueh'as will there skilled in the art to which it appertains to make and use the same.

My' invention has for its object to provide .a supplemental wheel rim which is capable of being quickly and easily applied to and removed from the wheels of motor propelled vehicles and which in its application does.

not. require defacing or the Wheel to which. I

it is applied...

, The m pnoved supplemental rim is for the purpose;-oif giving-increased traction and is of such a nature that when applied and the vehicle is *riinning'on a hard. roadbed, the supplemental rim is held out of action so that'the lugs or projections thereof wilhnot engage the road and the roadbed will not be I damaged'thereby. When a wheel having'the supplemental rim attached runs into soft ground and sinks slightly. the supplemental rim will bebrought into action and will then give not only increased traction, but

pacity. v

Thesuppleniental rims may he applied to both inner and outer sides of the wheels or to "one side only. In automobile service supplenienta'l rims will. usually be applied only to the outer sides of the wheels. but tor xheavy motor propelled vehicles or for wheels that are intended to he used at times for ner and outer sides of the traction wheels.

In the accompanying drawings which illustrate the invention. like characters,indicate like parts throughout the several views.

'leferring to the drawings Figure 1 is a side elevation showing a motor vehicle wheel equipped with my improved supplemental rims;

Fig. 3 is a fragmentary section on the line 33 of Fig. 1; anrl Fig. l is a section on the line of Fig. 1.

Specification of Letters Patent. Patgntefl Sept, 1 1918 Serial No. 207,227.

numeral 5 indicates the hub, (3 the spokes, 7 thefelly, 8 the metal rim. and 9-tl1e solid rubber tire. It will, of course, be understood that the wheel might be of the type provided with a pneumatic the so far as the present invention is concerned.

In the drawings the supplemental rims are shown as applied. both to the inner and outer sides of the Wheeh Each supplemental rim comprises a cylindrical portion or rim proper 10,4111 annular clamping flange 11, and radially projecting traction lugs 12 which parts are preferably'fornied integral,

although they might be separately formed and otherwise rigidlyconnected.

The cylindrical body portions 10 vof the supplemental rims. preferably do not engage with the projecting edges of the metal rim 8, but a portion close thereto so that the lugs 12 project radially outward of the said rim 8, outdo not project as far outward as the tread portion of the tire .9. The annular clamping flanges 11 are adapted to bear against the sides of the felly 7 and they are provided with inturned anchoring lugs 13' and bolt lugs 14- which latter project. ra-

dially inward and are perforated to receive nut-equipped clamping bolts 15 passed therethrough.

The clamping bolts 15 when thus inserted through the transversely alincd lugs ll of the two supplemental rims closely engage with the inner syutade of the folly 7 so that they in themselves hold. the supplemental rims centered in respect to the wheel and take the main shear produced by the weight of the load on the supplemental rims. However. the shear on the bolts 15 reduced to -a" .\'cr considerable extent, first, by the friction produced between the rims and telly when the nuts of the bolts are tightened and, second. by tho engagemcnt'of the anchoring lugs 13 with the inner surface of the folly.

In fact, the lugs 13 would, in themselves, take the shear and hold the supplemental rim centered in respect to the Wheel, even if the bolts 15 were not in direct Contact with the folly. However, the described arrangement is preferred. I

By referring to Fig. 4:, itwill he noted that the anchoring lugs 13 are notched so that they embrace the spokes and thus posithat. a re 'tively prevent circumferential creeping of with the nuts of den'iountab le rims when demountable rims are employed. These openings or clamping passages 16 permit aecessto the nuts of the deinountable rims, While the supplemental rims are in position.

It Will thus be seen that these supplemental riins' maybe applied to a ehicle Wheel Without putting, boring, or otherwise defacing or reconstructing the Wheel in any way, Also, as is evident, the rims may be quickly applied and quickly removed.

\Vhen a supplei'nental rim is to be applied to one side only, for example, to the outer side of the Wheel, there should he provided for engagement with the inner face of the telly to serve as an anchor for the bolts, an annular clamping flange such as one of the flanges 11 with a cylindrical portion 10 and lugs 12 left off.

The supplemental riins illustrated are of a type which could be best produced. by casting but the construction is such that it is capable of being readily stamped or pressed from sheet metal.

What I claim is:

1. The combination with a vehicle Wheel, of annular clamping flanges engageabl with the inner and outer faces of the wheel telly at leastone of said clamping flanges having an outstanding cylindrical portion affording a supplemental rim, and nut-equipped bolts passed through said clalnpingflanges and engaging the inner surface only of the heel felly, said riin equippedclamping flange having laterally projecting lugs that also engage the inner surface of the telly.

2. The combination with a Vehicle Wheel,

' of annular clamping flanges engageable with the inner and outer faces of the Wheel. telly, at least one of said clamping flanges having an outstanding cylindrical portion. ali'ording a supplemental rim, and nut-equipped bolts passed through said clamping flanges and engaging the inner surface only of the Wheel telly, said rim equipped clan'iping flange having laterally projecting lugs that also engage the inner surface or the telly, and the said cylindrical rim. forming portion having radially projeetii'ig traction lugs that tern'iinatc radially inward (a the outermost portion of the Wheel tire.

3. The combination with a vehicle Wheel,

of annular clamping flanges engageable with the inner and outer faces ofthe heel telly,

at least one of said clamping flanges having an outstanding cylindrical portion affording a supplemental rim, and nut-equipped bolts said annular claniping flanges and directly engaging the inner surface only of the Wheel telly, said annular chiniping flanges having laterally proje tii g lugs that also engage the inner surface oi the Wheel telly and are notched to embrace the spokes of the Wheel of annular clampingflanges engaging with the inner and outer faces of the Wheel telly,

5. flhe combination with a vehicle Wheel,

at least one of said clamping flanges having an outstanding cylindrical portion afiording the supplemental rims and further having laterally projerting lugs that are engaged with the inner surface of the wheel telly, and means for clamping said supplemental rims to said. Wheel.

In testiinonr whereof I ailix my signature in presence of two witnesses.

HUGH B. FOLEY.
